Abstract
Keywords- navigation, traffic information, route choice, traffic state, microscopic simulationNavigation system influences the route choice behaviours of individual road users and in turn determines the distribution of traffic load as well as the traffic state of the entire network, especially in cases of growing penetration rate of navigated vehicles. Therefore, this study conducts an in-depth investigation into the influence of traffic information and navigation on route choice and its impact on traffic state.
The experiments examined are based on microscopic vehicle simulation. In order to take realistic urban conditions into consideration, the road network of Hannover is chosen as the investigated network and built in a simulation model in detail. The simulation studies are conducted to analyse the different scenarios in regard to different fractions of dynamically navigated vehicles, re-routing frequencies of navigated drivers, different degree of knowledge about the current traffic state among travellers, and unexpected incidents.
The aim is to identify the feasible range of traffic management by providing information to navigated drivers. This is the base to specify the suitable and the preferred scope of dynamic navigation in urban areas and to point out the still required developments.
